Another newcomer to the Making of Psycho cast: James D’Arcy, who will take on the Anthony Perkins (the actor who played Norman Bates) role. Hitchcock and his crew toiled mercilessly over the crafting of the mentioned shower scene. In Le Cinéma selon Alfred Hitchcock, a book by François Truffaut, the Psycho director is quoted as saying, “It took us seven days to shoot that scene, and there were 70 camera setups for 45 seconds of footage.” Clearly, Hitchcock was a diligent artist; although Leigh’s role in Psycho was not a lengthy one, it is unquestionably one of the most powerful driving forces of the film. As such, Johansson has got a pretty meaty role ahead of her.

There are only a small handful of examples of films so powerful as to command the complete attention of full other works: this year’s Sundance Film Festival featured Room 237, a movie about the many ways to interpret The Shining. But even more celebrated than the Jack Nicholson classic is Psycho.Alfred Hitchcock and the Making of Psycho looks to be a truly reverent expression of everything this film has accomplished, and its new cast members add to the excitement.
